DETACHABLE HINGE.

Specification of Letters Patent.

Patented Feb. 22, 1916.

Application led October 20, 191,5. Serial No. 56,828.

To all whom t may concern.'

Be it known that I, WILLIAM R. TAYLOR, 'a citizen of the United States,.and resident of Racine, in the county of Racine and State of Visconsin. have invented 'new` and useful Improvements in Detachable Hinges, of which the following is a description, reference. being had to the accompanying drawings, which are a part of this specification.

rfhis invention has for its object to provide a spring hinge for screen doors or storm doors or the like which will permit of the door being quickly disconnected without the removal of screws or hinge pins or other securing devices by providing means for locking the hinge plates with relation to each other to take the pressure of the spring from them and permit the connecting plate to be disconnectedfrom the hinge.

This invention further has for its object to overcome certain difficulties which attend the manufacture and use of the detachable hinge covered by Patent No. 1,057,960 to Hector and Kline, dated April l, 1913.v

One object of the invention is to avoid a binding clamping action between the separate member or connecting plate and the hinge leaf engaged with it when attempting to disconnect them, but to so construct these interlocking parts that they may freely swing out of connection with each other when the spring tension is taken off of the hinge even though in doing so the door is swung open to its full limit.

Another object of the invention is to so construct the hinge parts of sheet metal as to utilize substantially the full length of the vhinge pin as a support for the coil spring and thereby permit the use of a spring of maximum length.

Another object of the invention is yto inclose the spring within a housing yformed by one of the hinge leaves to Vhide it from j view and protect it from engagement with clothing especially in case of the spring becoming broken. 4

Another `object of the invention isto provide such a hinge with hinge leaves provided with end lflanges in face to face Contact with 'each other and having the hinge` pin passing therethrough and alsohaving registering openings adapted to receive a locking pin for locking the hinge leaves together in their folded position, as when the door is removed, the separate member or connecting plate having similar end flanges and openings registering with the openings of the hingeleaf with which it connects to receive the locking pin for locking the. connecting plateto the hinge in case the spring becomes broken.

Another object of the invention is to provide Vthe hinge pin with loose bearing sleeves near its ends to prevent the spring contacting, therewith,

Another object ofthe invention is to improve various details of construction to add strength and durability and convenience of operation thereto.

.Vth the above and other objectsin view the invention consists in the detachable hinge as herein claimedY and all equivalents.

Referring to the accompanying drawings, in which like characters of referenceindicate the same parts in the different views, Figure l is a front viewv of a detachable hinge constructedv in accordance with this invention and applied to a door, the parts being in section; Fig. 2 is a plan view thereof; Fig. 3 is a sectional plan view thereof withthe door open and the bail loop engaged with the catch ready for permitting the doorto be detached; Fig. 4 is a plan view thereof with the-door and itsconnecting plate shown in dotted lines; Fig. 5 is a front view of the hinge with. the door and its connecting plate detached therefrom; Fig. 6 is a detailview showing the locking pin in position for locking the connecting plate with the hinge;v and, Fig. 7 is a detail view showinga modification.

In these ldrawings the detachable hinge of this invention is shown as consisting of hinge leaves or plates 10 and 1lI having end flanges 12 which project beyond the inner edges of said plates and fit Vtogether face to` face and-have a pivot pin 13 loosely passing l therethrough. The end flanges l2 of the hinge plate '10 fit against the inner faces of the end flanges of the hinge Yplate 1l and between them the sheet metal of which the hinge .plate 10 is formed is' bentv up and around to `ferm a somewhat cylindrical spring housing let which is open in the rear,

- coil spring 15 is fitted Within the spring i end thereof passes through a slot 16 of 'the spring housing and bears against the face `of the hinge plate 11. Loose bearingsleeves 17 surround the pivot pin 13 with' flaring ends engaging the ends of the coil spring, andv these sleeves serve as a bearing for the' end coni'olutions of the spring when they are contracted on opening the door, and thus prevent `abindingl of the spring againstv the pirotalY pin, with a consequent wear and pos'- s-ible injury to the spr-ing. One ofthe hinge plates has a pai-r of ears 18 cut therefrom; and bent up with openings therethrough to receive the hook ends of a V-shaped bail wire 19,and the other hinge has a hook lugi cut therefrom and bent up to forni a catch 20 to be engaged by the loop 19 for holding the spring plates in afiXed angularrelation against the action of the spring 15. Both the earsI 18 and the hook-shaped lug 2O liev in planes at right angles to the pivotal anis of the hinge, which insures their Strength and rigidity. v

The fianges 12 of the hinge plate 11 have engaging lugs21 bent outwardly therefrom in substantially the saine plane as the main portion of said hinge pla-te. member or connecting plate' 22 of substantially the same size and shape as the hinge plate 11 has upstanding flanges 28 at its ends corresponding with the upstanding vflanges 12 of the hinge plate and fitting against the outer faces thereof, and these flanges 23 havel shouldered recesses 24; to receive the lugs 21` and lit thereagainst. The hinge plate 11 has rearwardly projecting' lugs 25 at its outer edges which engage the outer edges of the connecting plate 22. The connecting plate 22 is thus heldl between the lugs 21 and 25' of the hinge plate 11 and embraces the hinge4 between its end anges 23.

The hinge plate and the connecting plate 22 are provided with suitable openings for connecting screws 26 by m'eansof which they may be Vattached respectively to the door and the' door frame.

Assuming that the hinge plate 10 is connected 'with a door` frame 27 and the connecting plate 22 is connected. with the door 28, as shown, the spring tends to keepy theV door closed as usual, but when it is desired to disconnect the door it is only necessary to open the door far enough to engage the loop 19 with the hook 20 and thus remove the spring press'ure'froin the door, and then by swinging the door toward its closed v position the hinge plate 11 beingheld by the loop has the connecting plate 22 stripped therefrom by first withdrawing it from engage'ment withfthe lugsv 25 and then from the A separate lugs-21, the end anges 23 thereof sliding-` freely from the end flanges 12 of the hinge as soon as the connecting plateis disengaged a from the lugs 25. If the door is to be replaced by another door the latter is provided with connecting plates 22 and is mounted on i the hinges bymerely ,sliding the end iianges alon the end flanges of the hinge plates g D b 1'1 until the shoulders of notches 24 engage the lugs 21. The door is then swung foute wardly su'liicieiit to bring the outer edgefof the connecting plates 22 within the hooklike engagement of the lugs2'5, and a stillfa'ntlier movement of theV door in this direction causes the hinge'plates 11 to swing and disengage: the .Y loopsr 19 `from the hooks 20 so thatzwlien the door is released. it .willf'be swungl closedby the hinge in the usual :man-` ner and the'substituti'on of one door for an-V other is complete without the removal of J screws oi" -avny'other loose part.`

It' is obviously immaterial whether the hinge plate 1G or the connecting plate 22 is connected to the door, though the forme-r connection is preferable in the event =of 4the` door being replaced by another,r as when` screeny doors and storni. doors are interchangeable, as insuch caseit isonly necesnecting plates on the door jainh as being neater and offeringy lessobstructi'on to.k the passage through the doorway when the door is removed. W/Vhen, however, the spring plates `1() are attached to the door jainb and the door is removed Without replacing ;it

with anotherthehilngemay be folded until 'l the plates 10 and 11 areapnroximately parallelfin which position openingsy 29 'in` theY end flanges 12 register with each other so that by dropping a headed pin.` or nail 8O therethrough the hinge parts are held in this folded' position.

lit/'ith the present construction the pivot'v pin 13 being mounted in turned-up `lianges at .the ends of the hingel plates 10 and llis allowed practical-ly the full length thereof:n`- 'i for receiving the spring 15, and' consequietly a. spring; of inaxiii'iuin' length may be employed and the sleeves v17 at the ends of the spring prevent its binding` and Wear` ing onthefpivot pin, and assure a freedom of action of the spring.

The housing 14 also protects the spring from engagement f with the clothes inthe eventof its becoming; broken and also adds to the appearanceof the device.- O bviouslya positivel connection between the hinge plate 11 and t-l-ie connect-f ing plate 22 is required to-maintain the hinge connectedv with the door whenlthe spring has i been broken, and for this purpose openings Blare` provided inthe end anges 23 et` iSC the connecting plate, such l openings registering with the openings 29 of the end flanges of the hinge plate 1l sothat when the headed pin 30l is dropped therethrough, as shown in rig. 6, it prevents the connecting plate from becoming disengaged from the hinge plate l1. i

Another provision for locking the parts together when the spring breaks consists in the forming of an opening 3Q in the hinge plate l1 registering with one of the screw openings of the connecting plate 2Q', so that when thespring breaks the screw maT be removed from said opening and passed through the registering openings ofy the platesll and 22 which will lock the parts together. The repair of a broken spring may be simpl)7 made as the hinge pin 13 is not upset at its ends but is free to be driven out of the hinge members so that the broken spring may be removed from the rear of the spring housing and replaced with a new spring and the hinge pin4 returned, it being impossiblefor the hinge pin to be lost when the hinge is in use, as the end flanges 23 of the connecting plate 22 fit against both ends thereof.

In mounting the hinge the connecting plate 22 serves as a guide as the shoulders of the notches 24 thereof are so placed as to lie in the plane of the meeting edges of the door and its door jainb. This plate is placed against the door and moved toward the edge thereof until the shoulders of the notches 24 engage a rule or other straight edge held against the edge of the door and projecting slightlv bevond the face thereof. In this position of the plate the positions of the screws are marked through the screw openings, and when the plate is attached the hinge is engaged therewith, and with the door in place and the loop 19 disengaged from the hook 2O the hinge plate lOwill be in its proper position so that the positions of the screws ma37 be marked through the .screw openings thereof.

lt is obvious that the rearwardlyT projecting engaging lugs 25 ma;T be dispensed with b v forming the notches 24 with hoolrlike shoulders 24, as shown in lig. 7, so that the opposite shoulders of the notches engage both sides of the lugs 21.
